SPECIFXCATION forming part of Letters Patent No. 794,030, dated July 41, 1905'). Application liled October 26, 1904. Serial No. 230,065.

To a, whom, it may concern:

Be it known that :l, 'lnoiuAs Lmunnrrn, a citizen oi. the United States, and a resident of ltachel, in the county oi Randolph and State of North Carolina, have invented a new and improved Water-Vl hcel, oi. which the following is a full, clear, and exact description.

This invention relates to improvements in water-whecls oi the undershot type, the object being to provide a simpleand novel means for positively moving the blades outward to receive the waterqn'essurc and moving them inward or into the wheel-body upon leaving the water, thus preventing back pressure.

i will describe a watcr-whcel embodying my invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters oi re'ierence indicate corresponding parts in all the figures.

Figure 1 is a sectional elevation of a water- Fig. 2 is a section on the line :1: :1; of Fig. 1. Fig. 3 is a section through the frame with the wheel removed. ll ig. l is a plan. Fig. 5 is a section through one 01' the blades. Fig. 6 isa section on the line ;i 7 of Fig. 3, and Fig. 7 is a section through the regulating-gate.

Referring to the drawings, 1 designates the wheel-casing, with the lower portion of which the water-chute 2 coi'nmunicates. Mounted in the casing is the water-wheel 3, which, as here shown, consists oil a practically solid block having at suitable distances apart radial slots or openings t, which extend from a point near the wheelshait 4c and open outward, and in these slots the blades 5 are designed to slide. These blades 5 preferably consist oi metal plates and they are connected to the ends of the wheel by means of curved ari'ns 6. The ends oi the blades are bent at substantially right angles to the body, as indicated at 5, and these bent portions slide in recesses o formed in the cndsoi' the wheel. These arms (3 have their ends mounted to swing in the ends oi the wheel and travel in circular recesses 5", formed in the inner side of the easing, and carried by said. arms adjacent to their connection with the blades are rollers 7, which extend into a recess, the upper portion oi which is .lT OXIDO/(l in the inner side oi the casing, as indicated at 8, while the lower portion is formed by cam-plates 16, carried on plates 9, mounted to slide vertically on the casing. The completed recess is siibstantialtv oval in form, and the wall thereof forms a cam against which the rollers 7 engage to force the blades outward when in a lowermost position, as indicated in Fig. 1. As the blades move loosely in the slotsthc arms 6 will serve as braces.

Attached to the inner sides of the plates 9 are tl-shaped metal plates 10, which form the inner wall of the cam-recesses. The plates 9 have beads '11, which engage in vertical channels 12, formed in the outer sides oi the easing, as clearly indicated in Fig. 4, and the upper ends oi? these plates 9 are connected by a cross-plate i3 and firmly secured together by means oi bolts 14. The lo wcr ends 0 i the plates 9 carry a gate 14, which is concaved on its upper side, and this gate is movable in an opening 15 in the lower portion of the casing. Hy moving the plates 9 upward it is obvious that the gate 14* will be moved upward to reduce the outlet or OpOlllllg through which water may pass to operate upon the blades, and by moving said parts upward the recess comprising the parts 8 and 16 will be reduced in length, thus regulating the outward movcmcnt of the blades. Mounted to swing on the bottom wall oi the chute 2. is a deiieetonplate 17, the inner or Free end oi which engages with a strip 18 on the gate 14, and therefore this plate will he moved up and down with said gate, so as to direct the water thereto. The plates ii of the gate may be raised and lowered by any suitable means. i have here shown for this purpose the plates 9 as provided with racks it), meshing with pinions 20, mounted on arms 2] having angular shai't portions 5.52, with which a crank may be engaged.

.In the operation as the water passes through the chute it will cause a pressure on the blade or blades that may be extended from the wheel, and as the wheel rotates the camwails oi the recesses 8 and 16 will cause an inward movement of the Luiwardly-moving blades and cause an outward, movement oi the lower blades. 1 have here shown the gate 14: asdei'achably connected to the side plates 9. The connec ting devices consist of loop-bars 23, having swinging connection with the plates 9 and adapted to pass underneath the ends of the gate.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent- 1. A water-wheel comprising a casing having openings in its side walls, plates mounted to slide in the casing and having curved portions,the walls of said openings with the curved plates forming substantially oval tracks, a wheel mounted in the casing and having radial openings, blades movable in said openings, arms having swingin connection with the ends ot' the wheel and also having swing ing connection with the inner ends of the blades, rollers on said arms for engaging the walls of saidtracks, and a chute leading to the lower portion of the wheel.

2. A water-wheel coimirising a casing, a chute leading into the lower portion thereof, a wheel mounted in the casing, blades movable radially out of and into said wheel, adjustable means for causiiig such inward and outward movements, and a vertically-adjustable gate in the lower portion of the casing directly under the wheel.

A water-wheel comprising a casing, a chute communicating with the lower portion thereof, a wheel arranged in the casing, radiall y-movablo blades carried by the wheel, adjustable means for causing inward and outward movements of the blades, a gate in the lower portion of the casing directly under the wheel and adjustable toward and from the whee, and a deflector-plate mounted to swing in the chute and operating with said gate.

i. A water-wheel comprising a casing, a chute communicating with the lower portion thereof, the said casing being provided with openings in its side walls, the upper ends of said openin being of oval Form,platesmounted'to slide on the outer sides of the casing, U-shaped plates secured to the sliding plates within the openings, a wheel mounted in the casing and having radial openings, blades mounted to slide in and out of said openings, arms having swinging connection with the ends of the wheel and having pivotal connection with said blades, rollers carried by the arms for engaging in said openings in the end walls of the casing, and a gate in the lower portion of the casing adjustable toward and from said wheel.

A water-wheel comprising a casing, a chute communicating with the lower portion thereof, said casing having an opening at the lower end, a gate adjustable in said opening directly under the wheel and having a concaved upper side, a wheel mounted in the easing, blades carried by the wheel and movable radially into and out of the same, and adjust able mechanism for causing said inward and outward movements.

In testimony whereof l have signed name to this specification in the presence of two subscribing witnesses.
